PentaEye gives your iPhone camera more lenses, won't fit in your pocket
While Will.i.am is off trying to make the ultimate iPhone-camera case, you can jump to the head of your class with the new TurtleJacket PentaEye case that just hit the market. The case includes a nice 5-lens wheel that lets you switch between a number of lenses in a fairly quick amount of time.
The case, which is currently only available for the iPhone 5, ships with a fisheye lens, wide-angle lens, telephoto lens, and macro lens, as well as a nifty strap holder and tripod mount. If that's not enough lens for you, the case also has a built in 37mm mount so you can attach other lenses that you've acquired over the years.
The TurtleJacket PentaEye will set you back 2080 Hong Kong Dollars (about $268.39 US at current exchange rates), and it may convince you to put the money towards an actual DSLR, but doing that would also mean losing access to all those nifty Instagram filters. Heck, no one wants to lose access to the simple Instagram upload features, either.
While your results may vary and the quality of your iPhone's photos may not turn you into an award-winning photographer overnight, it's always niece to have access to a couple more lenses at moment's notice.
